SHAWNEE, Kan. -- A Kansas City woman is dead following a single-vehicle crash in Shawnee early Monday morning.

Edwina Bates, 48, crashed into a power pole then into a tree near 75th and Westgate around 4:29 a.m.

Authorities have not said what caused the crash. The sergeant on scene Monday said speed was probably a factor, but the traffic unit is working on forensic mapping to determine the official cause.

Bates' car was so mangled the sergeant said he couldn't determine the make or model.

Kansas City Power and Light was also on the scene to repair the pole. Traffic was shut off on 75th Street from Long to Richards Road. One eastbound lane remained open, but all westbound lanes were closed
